Therefore, it should be noted that the inner filter cartridge described herein can be used as a composite filter in combination with various materials of different functions as well as a single filter as part of the assembly with the outer cartridge housing 100a.

The filter cartridge 100b forming the cartridge assembly is embedded in the outer housing such that the inflow water flow passage 155S is formed in the outer circumferential direction, and has a filter material having a functional active ingredient at each of the upper and lower ends thereof with an outlet and an inlet. Built.

As used herein, a filter material having a functional active ingredient, as described above, is a specific material used to impart specific functionality such as providing antimicrobial activity to influent, maintaining a proper pH, and containing a proper mineral component. It means the filter material containing the component.

Specifically, the filter material may be a ceramic material calcined to elute silver ions using zeolite, a natural material or a ceramic material including a hydroxide compound that emits hydroxide ions (OH ⁻ ), shells or coral sands (coral). Various filter materials, such as mineral component eluting material, such as may be employed, the shape of the filter material may be a non-uniform shape or a ceramic ball shape of the natural material.

The upper and lower ends of the inner filter cartridge are formed with outlets and inlets, respectively, and the inlets and outlets on both sides of the upper and lower ends are composed of peripheral passages 110h and 130h spaced apart by a predetermined radius from the center. Non-woven filter (120a; 120b) may be installed on the inlet and outlet side for filtering and adjusting the flow rate of purified water flowing in or out.

Inflow water flows through the internal filter cartridge containing a variety of useful eluents to keep the content of the eluent constant while allowing the influent to flow directly into the internal cartridges, while the external housings and internals do not go through the internal cartridges separately. Flow into the space between the cartridges.

In other words, the inflow water is introduced through the inflow port 110 of the outer housing and is introduced through the first inflow water inflow space 110S at the bottom of the outer housing 100a, and a portion of the inflow water passing through the filter cartridge inflow passage 110h is While entering the inner filter cartridge through the central passage 115 of the inlet of the inner filter cartridge, another part of the inflow water is circumferential direction between the inner filter cartridge and the outer cartridge housing through the peripheral passage (110k) of the inlet of the inner cartridge It is introduced through the flow passage formed in the (155S).

On the outlet side of the internal filter cartridge, the purified water that has passed through the internal cartridge and contains a high content of active ingredient and the purified water that does not change the content of specific components are mixed with each other by passing through the flow passage 155S without passing through the internal cartridge. In other words, the mixed purified water keeps a certain active ingredient constant.

However, according to the inflow pressure of the influent, since the active ingredient content of the influent that passes through the inner cartridge is greatly affected, it is difficult to keep the effective ingredient content constant through the inner cartridge. To this end, a venturi tube 170 is installed on the outlet side of the internal cartridge 100b to maintain a constant outflow amount even with a change in inflow pressure of the inflow water.

Since the venturi tube 170 is directly connected to the upper outlet side center passage 125 of the inner cartridge and communicates with the flow passage 155S outside the inner cartridge 100b, the venturi tube 170 passes through the inner filter cartridge 100b. It has a function of mixing the purified water and purified water without passing through the internal filter cartridge, the mixed purified water is passed through the peripheral passage 130h on the outlet side side in the first outlet space 170S (the second outlet space of the external cartridge housing 100a) 130S) and is discharged to the outside through the outlet 130.

The venturi tube 170 has a shape in which a central micropath and flare-shaped passages on both sides are connected to each other, and a central passage of the inner cartridge 100b is connected to the central micropath, and the flare passage on one side is a flow passage 155S. In contact with the flow path 155S, the purified water passing through the inner cartridge is sucked by the pressure dropped according to the pressure drop effect (venturi effect) generated when the inflow water passing through the flow passage 155S passes through the fine passage of the venturi tube. The purified water moved to and mixed with, since the purified water as much as the pressure drop of the purified water passing through the venturi tube 170 through the distribution passage (155S), the mixed purified water has a constant active ingredient content.

On the other hand, the lower inlet side of the inner filter cartridge is formed in the inclined form 150 with the central passage as a peak to prevent the phenomenon that the inflow efficiency is reduced by the generation of bubbles on the surface during the inflow of the inflow water.

According to the above-described configuration, the present invention is for a water purification system configured such that the purified water passing through the filter cartridge housing containing the active ingredient maintains a certain amount of the active ingredient and does not have a large change in the content of the active ingredient even after a long period of water purification. An assembly with a filter cartridge and a filter housing for a water purification system employing the same is provided.
